Trial Outcomes & Findings for Efficacy and Safety of Lacosamide as Adjunctive Therapy in Subjects ≥1 Month to <4 Years With Partial-onset Seizures (NCT NCT02477839)

NCT ID: NCT02477839

Last Updated: 2021-07-01

Results Overview

The change in ADF of electrographic partial-onset seizures as measured on the End-of-Maintenance Period video-electroencephalogram (EEG) compared to the End-of-Baseline Period video-EEG. Seizure frequency was analyzed using an analysis of covariance (ANCOVA) with terms for treatment, pooled randomized age stratum, pooled center, and Baseline seizure ADF. Seizure ADF was log transformed using the transformation of ln(X+1), where X is the seizure ADF. Baseline seizure ADF was log transformed. Least squares means were based on log-transformed data of the full ANCOVA model.

Participant Flow

The study started to enroll patients in June 2015 and concluded in May 2020.

Completed study was defined as participants who had "Completed study participant" selected as status at termination. The total number of participants who completed the study comprises of those who completed the Transition Period and the ones that completed the Taper Period after completing the Maintenance Period. Participant Flow refers to the SS.

PRIMARY outcome

Timeframe: End-of-Baseline Period (Day -3 to Day 1) to End-of-Maintenance Period (Day 24 to Day 27)

Population: Full Analysis Set (FAS) included all study participants in the Safety Set (SS). The analysis consisted of all study participants in the FAS who had at least 48 hours of interpretable recordings during the EOB Period video-EEG and the EOM Period video-EEG.

The change in ADF of electrographic partial-onset seizures as measured on the End-of-Maintenance Period video-electroencephalogram (EEG) compared to the End-of-Baseline Period video-EEG.

PRIMARY outcome

Timeframe: From the Baseline Period (Day -7) to the End of Study Visit (up to 93 days)

Population: The Safety Set (SS) included all randomized study participants who took at least 1 dose of study medication.

An adverse event (AE) is any untoward medical occurrence in a patient or clinical study participant, temporally associated with the use of study medication, whether or not considered related to the study medication. An AE could, therefore, be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of study medication.
